Daikin furnace repair in Marietta typically runs between $150 and $700 depending on the part that failed, and most jobs are done in a single visit. We’re an independent Daikin service provider, which means we work on every Daikin furnace line out there without being tied to factory pricing or corporate service schedules. If your Daikin furnace is throwing an error code, short-cycling, or blowing cold air, call (229) 514-0545 and we’ll get a tech to your door with a written price ready before any work starts.

How Daikin Products Fail – and How We Fix Them
Daikin builds solid equipment, but every furnace line has its patterns. We see the same handful of failure modes across Marietta neighborhoods, from older homes near the Square to newer builds out toward Kennesaw Mountain. Here’s what actually shows up on Daikin service calls:
- DM96VC and DM97MC gas valve solenoid failures. These modulating furnaces use a gas valve that adjusts flame output in fine increments. After five to seven years of Marietta’s damp winters, the solenoid windings can degrade and the valve won’t hold its modulation signal. The furnace will fire, then drop out repeatedly, sometimes locking out entirely. We replace the gas valve assembly with an OEM Daikin part and verify gas pressure at both low and high fire before we leave.
- Dual-chamber heat exchanger stress on the DM96VE line. The two-stage burners on this series put uneven thermal load on the primary heat exchanger, especially in homes where the previous owner skipped annual filter changes. What starts as a hairline crack gives you a faint metallic odor and a rollout switch trip that’s hard to reproduce. We pressure-test the exchanger with a combustion analyzer before we ever quote a replacement, because you shouldn’t pay for a new one if the old one is still sound.
- ECM blower motor module failures across multiple Daikin lines. Daikin uses electronically commutated motors (ECMs) on variable-speed units, and when the control module on the motor fails, the blower either runs at a single fixed speed or refuses to start. Homeowners often mistake this for a thermostat problem. We bench-test the motor, check for the telltale 13-blink fault code, and offer both OEM module replacement and a lower-cost factory-remanufactured option if the warranty has lapsed.
- Ignitor burnouts on DM80SE and DM80HE single-stage units. Daikin’s silicon nitride ignitors are durable, but voltage spikes from Marietta’s summer lightning storms are not rare. When the ignitor cracks, you get a furnace that glows but never lights, or one that fails on the first cold morning of November after sitting idle for months. This is usually a straightforward fix: we replace the ignitor, test the flame sensor in the same visit, and check the incoming voltage to rule out an underlying electrical issue.
- Flame sensor carbon buildup in high-efficiency units. The DM96VC and DM97MC models pull combustion air from outside, which in Marietta means they ingest pollen in spring and fine red clay dust in summer. That contaminant film coats the flame sensor until it sends a false “no flame” signal and the furnace shuts down seconds after ignition. We clean the sensor with a non-abrasive pad, test flame signal with a microamp meter, and show you the before-and-after reading right on the job.

Our Daikin Furnace Repair Process
Here’s how a Daikin furnace repair job goes when you call Halden Heating and Air Marietta:
- 1
You call or book online, and you talk to a real person. We answer 24/7. You describe the symptom, we give you a live arrival window, and you track the tech to your door – not a four-hour guess.
- 2
The tech arrives, introduces himself, and confirms the written price for the diagnostic. That price is locked before any panel comes off. No surprises at the door, no “well, while I’m here” upselling.
- 3
We run a point-to-point diagnosis on the Daikin unit. We pull the error code history from the control board, check gas pressure, test the ignitor and flame sensor, and isolate the failed component. For Daikin modulating furnaces, we verify the thermostat is actually communicating with the furnace control board, because a dropped communication signal on a Daikin One thermostat can mimic a furnace failure.
- 4
We give you a written repair price before we touch a single tool. That price includes the part, the labor, and the guarantee. You approve it or you don’t – no pressure either way.
- 5
We make the repair with OEM Daikin parts or factory-quality aftermarket parts. If your unit is still under Daikin warranty, we coordinate the warranty paperwork and only charge for labor plus any parts the warranty won’t cover. We don’t void warranties by installing mismatched parts.
- 6
We test the furnace through multiple full heating cycles. We verify both stages fire correctly on two-stage units, confirm the blower ramps up and down properly, and check for any rollout or combustion issues. Before we pack up, you get a summary of what we found, what we fixed, and what the guarantee covers.
Every Daikin repair carries a written guarantee. If the repair fails within the coverage window, we come back at no charge – automatically, no phone tag, no arguing. That’s the 365-Day Done Right Promise, and it’s part of The Relay Standard on every job.

AfterWhat Daikin Furnace Repair Costs in Marietta
Here’s what Marietta homeowners actually pay for common Daikin furnace repairs, based on what we quote week to week:
- Flame sensor cleaning or replacement: $150 – $250
- Ignitor replacement: $200 – $400
- Gas valve replacement (single-stage): $400 – $650
- Gas valve replacement (modulating DM96VC/DM97MC): $550 – $700
- ECM blower motor module: $350 – $650 depending on OEM vs remanufactured
- Heat exchanger replacement (under warranty): labor only, typically $350 – $550
- Heat exchanger replacement (out of warranty): $500 – $700, and at that point we’ll give you an honest repair-vs-replace conversation
The biggest price drivers are whether your unit is still under Daikin’s parts warranty and whether you have a single-stage, two-stage, or modulating unit. Modulating furnaces have more expensive gas valves and control boards, full stop. We give you the exact written price before any work begins, and estimates are always free. Call (229) 514-0545 for a quote on your specific Daikin model.
Why Marietta Homeowners Call Halden Heating and Air Marietta for Daikin Work
We’ve been running service calls in Marietta long enough to know where Daikin furnaces are in this market – from the 1970s ranch-style homes east of the Square to the new subdivisions pushing west. Andre Fuller trained on HVAC fundamentals at Los Angeles Trade-Technical College and spent nearly two decades turning wrenches before building Halden Heating and Air on one rule: put the price in writing before anyone opens a panel. Straight answer, written price, done right. That rule never takes a day off.
We’re certified to service Carrier, Trane, and Lennox equipment too, which matters less than you’d think until your Daikin furnace dies at midnight on the coldest week of January and you need someone who can read any unit’s wiring diagram without blinking. Our techs arrive in uniform, background-checked, with a live arrival time you track on your phone. And every repair, no exceptions, comes with a written guarantee. If it fails within the coverage window, we return free. That commitment is part of The Relay Visibility Guarantee every Halden job falls under.
FAQs
No, as long as the repair uses compliant parts and doesn’t involve unauthorized modifications. We follow Daikin’s warranty terms on every job, and if your unit is still covered, we’ll handle the warranty paperwork and only charge for labor and any non-covered parts. An independent Daikin service provider working on your furnace does not void the manufacturer warranty.
We offer same-day service for most Daikin furnace repairs in Marietta, and our phones are answered by a live person 24/7. If your furnace is down during a cold snap, call (229) 514-0545 and we’ll give you a straight answer on when a tech can be at your door – with a live arrival time you can track.
If the heat exchanger is cracked and the unit is over 12 years old with a lapsed warranty, replacement often makes more financial sense than a $700 repair on a furnace you’ll likely replace within two or three years anyway. We’ll give you the repair price and an honest comparison to what a new Daikin or Carrier system would cost installed, and let you decide with real numbers in hand. No sales pitch, just math.
Common parts like ignitors, flame sensors, and single-stage gas valves are usually available same-day through local supply houses. Modulating gas valves and proprietary control boards for the DM96VC and DM97MC lines sometimes require an overnight order, but we’ll tell you the parts lead time during the diagnostic so you’re never left guessing. If a part is backordered, we’ll make sure you have temporary heat while it ships.
Blowing cold air on a Daikin furnace usually points to one of three things: a failed ignitor, a dirty flame sensor, or a control board that isn’t sending the signal to ignite. The good news is all three are repairable, and the diagnostic flat price we quote covers finding the real culprit – not a guess. Call us at (229) 514-0545 and we’ll get you an exact answer.
